5,500-year-old ‘Polish pyramids’ discovered in western Poland reveal Neolithic engineering

Polish archaeologists have found two megalithic tombs over 5,500 years old that teach us more about the burial practices and engineering abilities of one of Europe’s earliest agricultural societies. The structures—sometimes called “Polish pyramids” or “giants’ graves” due to their triangular, monumental shape—were uncovered in the village of Wyskoć, in General Dezydery Chłapowski Landscape Park in the Wielkopolska province.

The discovery was made by archaeologists from Adam Mickiewicz University in Poznań during a field survey regularly conducted using remote sensing technology. The tombs, whose existence was confirmed through excavations, were constructed by the Funnelbeaker Culture, a Neolithic society characterized by pottery and monumental burials. The new findings are the second of their kind to be identified in the Wielkopolska region, the first being in 2019.

Up to 200 meters in length and reaching a height of approximately four meters, the tombs were constructed in elongated trapezoidal forms, with wide, high eastern fronts narrowing into tapering, low western “tails.” Such an arrangement, archaeologists believe, could have had symbolic significance and indicates an advanced understanding of spatial design. The structures were aligned to the cardinal directions, a sign of a sophisticated understanding of astronomy.

The tombs were framed with huge stones, some of which weighed up to 10 tons. Although they lacked modern equipment, the builders were able to transport these boulders, likely with low-technology but efficient methods using sledges and human power. Most of these stones have been lost or moved over the centuries, as surrounding peoples repurposed them. “Humans have needed stones for thousands of years, so naturally they took them and split them,” Artur Golis, Wielkopolska Province Landscape Parks Complex head specialist for nature and landscape conservation, told PAP. “Consequently, the objects have been quite heavily degraded.”

Even though the Funnelbeaker people seem to have lived in fairly egalitarian communities, members of significant social or spiritual importance—such as tribal leaders, shamans, or priests—were buried inside the tombs. The tombs likely each held a single body, laid on its back with extended legs to the east, and grave goods like pottery, stone axes, copper ornaments, or opium vessels.

“In this case, the skeleton probably no longer survives, but the burial offerings might,” Golis said.

Five probable locations were pointed out by the archaeologists during their survey, two of which ultimately revealed tomb structures. One of these has been excavated so far, but researchers hope the remaining locations will provide more information about the social lives and spirituality of Neolithic Poland.

Most of the monuments of this type have been found in the Kuyavian region in northwestern Poland, and therefore, the Wielkopolska discovery is exceptionally significant for regional history. These “Polish pyramids” are some of the largest prehistoric burial structures in Poland and are rare evidence of the earliest European monument construction.

For now, the site is closed to the public while excavations continue. Any future plans for public access will depend on preservation assessments and archaeological findings. These ancient monuments are reminders of a society that, though in the Stone Age, was remarkably ingenious, socially organized, and reverent in its respect for the dead.
